This is fun in a bike-nerd kinda way. For your enjoyment, a 1945 industrial film on the manufacturing of Raleigh bicycles. There was little importing of components at Raleigh in 1945, most things were produced from raw materials in their Nottingham factory. By 1949, Raleigh was manufacturing 750,000 bicycles per year and most of those were for export.

While I'm on the subject of Raleighs in the movies, there's another commercial film that features the famous British cycle manufacturing icon. Saturday Night and Sunday Morning is a 1960 movie starring Albert Finney as a disaffected youth on the prowl and working as a machinist in Raleigh's Nottingham factory. The film is dreary and the only thing that I can remember about it are the shots of the factory and the bicycles. Finney's character turns crank spindles on a lathe and rides a beautiful Raleigh 10 speed with a Benelux derailleur and Bluemel mudguards.
